Abstract

An electronic cigarette and a method for controlling atomization of the electronic cigarette are provided. The electronic cigarette includes an atomizer and a battery rod assembly. The atomizer is formed by detachably connecting a liquid cup assembly and an atomizer core. A control unit is provided to be electrically connected to the atomizer and the battery rod assembly. A conductive cartridge that is conductive is sleeved on the battery, and the suction nozzle and the conductive cartridge can be conducted. The control unit controls the battery to supply power to the atomizer to atomize cigarette liquid when detecting that the suction nozzle is conducted with the conductive cartridge, which effectively prevents an automatic operation of the atomizer and avoids a waste of the cigarette liquid and the energy while facilitating the user operation.
